The UPSC exam pattern has evolved significantly, shifting from a primarily subjective format to a greater emphasis on objective-type questions and analytical thinking. Over the years, the introduction of the CSAT and changes in mains examination trends reflect a focus on assessing a candidate's overall aptitude rather than rote memorization. Recent years have also seen an increase in the integration of current affairs into the examination, making it essential for aspirants to stay updated. Thus, candidates must adapt their strategy to align with these evolving patterns.
